Multiple vulnerabilities in HP BladeSystem c-Class Virtual Connect Firmware

1) SRTP Memory Leak

EUVDB-ID: #VU5212

Risk: Medium

CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-3513

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information and cause denial of service.

The vulnerability exists due to a parsing error within DTLS SRTP extension in OpenSSL. A remote attacker can send a carefully crafted handshake message and free up to 64k of memory or cause denial of service conditions.

Successful exploitation of the vulnerability may allow an attacker to obtain potentially sensitive data, stored in system memory, or cause the affected service to fail.

Mitigation

Install update from vendor's website.

2) Information disclosure

EUVDB-ID: #VU5214

Risk: Medium

CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:F/RL:O/RC:C]

CVE-ID: CVE-2014-3566

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to usage of insecure SSLv3 protocol in OpenSSL. A remote attacker can force the current connection between user and server to be downgraded to SSLv3 protocol and then use padding-oracle attack on Cypher-block chaining (CBC) mode to decrypt encrypted communication.

Successful exploitation of the vulnerability may allow an attacker to read encrypted communications in clear text.

Note: The vulnerability is known as POODLE.

Mitigation

Install update from vendor's website.

3) Session Ticket Memory Leak

EUVDB-ID: #VU5213

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2014-3567

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause denial of service.

The vulnerability exists due to an error when handling integrity of session tickets in OpenSSL. A remote attacker can send a large number of invalid session tickets and cause denial of service conditions.

Successful exploitation of the vulnerability may allow an attacker to perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.
